Answer:
You may use cos 60° or sin 30°. Let's use cos 60°.
cos 60° = opp/hyp = (2 mm)/j
or
j = (2 mm)/(cos 60°) = 4 mm
Answer:
The answer is my Butt #1 .............
Draw two straight parallel lines and label with units and arrow as the end
Draw a tick mark through both lines and label with given ratio.
Start with 0 and 0 on each number line.
Label the units of each number line.
Vol of sphere =4/3πr³
let the radius of cone be x.
vol of cone =1/3πx²h
when h=r, =1/3πrx²
since they have the same volume,
4/3πr³=1/3πrx²
4πr³=πrx²
x²=4r²
x=2r (radius)
